Development of a fan filter unit test standard, lab validations, & applications across industries


After numerous peer reviews across industries, this standard energy and airflow test method for FFUs is used to quantify total pressure efficiency and power consumption of FFUs across a range of operating conditions—defined in terms of actual airflow rates (or velocity) and pressure loss throughout the recirculation system. LBNL has tested 17 different FFUs from manufacturers in Asia, Europe, and North America. Author(s): Xu, T.
